HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 521,923, dated June 26, 1894.

y Application tiled December 11, 1893.l Serial No. 4935351. (No model.)

To a/ZZ whom it may concern:

Be it-known that I, ROBERT H. WALTON, a citizen of the United States, residing at Walnut Springs, in the county of Bosque and State of Texas, have invented a new and useful Hay-Press, of which the followin gis a speciication. o

My invention relates to improvements in hay-presses, and has particular reference to improvements in the plunger and the mechanism connected therewith `for operating the same.

The objects of my invention are to produce a mechanism, the plunger of which is operated by the oscillating movements of the sweep-arm, and to so connect the two that the plunger will be caused to operate twice to each movement of the sweep-arm, wherebyI accomplishja maximum number of rams or tamps to a minimum number vof movements of the sweep-arm.

With these and other objects in view the invention consists in certain features of construction hereinafter specied and particularly pointed out in the claims.

Referring to the drawingsz-Figure l is a perspective view of a press embodying my improvements. Fig. 2 is alongitudinal section through the meeting end of the plunger and the oscillating sweep-arm. Fig. 3 is a plan view of the connecting ends of the plunger and sweep-arm showing the parts in the position they occupy after the first movement of the plunger. Fig. i is a similar view showing the parts in the position they occupy after the second movement of the plunger. Fig. 5 is a detail in perspective of the switch or shifting-plate.

Like numerals of reference indicate like parts in all the igur'es of the drawings.

In practicing my invention I preferably construct a press-box or baling-chamber with four longitudinal :beams 1 connecting the same by transverse bars 2 vand vertical posts 3, the whole forming a framework in which are located the walls 4 of the press-chamber. The beams 1 are continued beyondthe front end of the press and are connected by means of transverse beams y5 which are arranged vertically opposite each other. A fulcrum-bolt 6 is passed through the two beams 5 and upon the same there is fulcrumed the sweep '7.

Thissweep 7 is provided with a metal ferrule 8 at its inner end, said ferrule having a slot 9 formed in its opposite sides and extending around the inner rounded end of the sweep. The slot it will be observed is T- shaped in cross-section, and the same receives the outer T-end 10 of a shifting-plate 11. The shifting-plate 11 is triangular and lo` cated 'and pivoted at 11a within a horizontal slot 12 formed in a bifurcated conical fel-rule with which the front end of the plunger 13 is provided. The rear or widened end of the shifting-plate 11 is slotted or recessed ybetween its side edges, as indicated at 14, and a limiting bolt 15 passes downwardly through the ferrule and through the slot or recess in said plate, whereby vthe plate can onlyoscillate a certain distance.

In one of the cross-timbers 16 connecting a pair of beams 1 there is located an eye-bolt 17, and to this is vconnected loosely at '18 a rod 19, whose forward free end passes through an eye 20looated upon the plunger-rod. A coiled-spring 22 is interposed between the guide-eye on the plunger and the inner end of` the'rod, and being ot' the expansive pattern serves to normally return the plunger when otherwise released. Y

This completes the construction of the invention with the exception of suitable braces 23 which lead from the cross-beams 5 to the longitudinal beams 1.-

The operation of the invention is as follows:-Taking the parts as shown in Fig. 1 the sweep is carried around until in linewith the machine, and during its travel the rounded end of the sweep bears against the rounded end of the plunger and forces the latter rearward so as to pack the hay contained therein into the press. From the position in alignment with the machine the movement of the sweep is continued, and after the center has been passed the coiled spring of the plunger causes the plunger to move backward, the said movement being limited by the ends of the slots in the sides of thesweep.

vFrom this point the movement of the sweep is continued, andthe side of the sweep acting againstthe end of the plunger serves to repress the same. or force it inward. The movement is continued until the sweep passes beyond a right angle to the plunger when the ICO the baling press.

spring again retracts the plunger, throwing the same outward, whereby the plunger is in position for the third stroke. The plunger is now oscillated in a reverse direction and again the end of the sweep operates upon the end of the plunger to force the latter to the front, and the movement is continued until the sweep passes beyond the longitudinal center, when the spring again acts to retract the plunger, and the sweep continuing its movement passes beyond a right-angle and for the fourth time forces the plunger into It will be seen that the shifting-lever working upon its pivot swings to opposite sides of the plunger so that its T-end is adapted to operate irst'on one side and then on the remaining side thereof alternately.

From the foregoing description in connection with the accompanying drawings it will be seen that I have provided a very simple construction of power mechanism, the same being designed for use upon baling-presses, and which is powerful, being of the lever pattern, and is so arranged that with each oscillation of the sweep the plunger is operated twice.

I do not limit my invention to the precise details of construction herein shown and described, but hold that I may vary the same to any degree and extent within the knowledge of the skilled mechanic.

Having described lmy invention, what I claim is l. In a baling-press, the combination with the baling-chamber and its plunger tapered at its outer end, of a sweep fulcrumed between its ends at the front end of the plunger and provided with inner tapered guides at opposite sides thereof, a retracting spring for the plunger, a triangular plate pivoted between its ends in a slot of the plunger, said plate having its front end made T-shaped to engage the guides in the sweep, and means for limiting the oscillations of the plate, substantially as specified.

2. In a baling-press, the combination with the press frame, comprising a series of horizontal beams connected at their outer ends, a bolt passing through the transverse beams, a sweep intermediately pivoted thereon and having an inner tapered end provided atopposite sides with a slot continuing from side to side and around said end, of a plunger arranged in the chamber and having an outer tapered end provided with a horizontal slot, a pivot-bolt passed through the slot, a triangular shifting-plate pivoted upon the bolt and having a front end loosely engaging the slot in the sweep and its rear end recessed, a limiting bolt passing through the slot and the recess, the eye on the plunger, an eye-bolt passed through a part of the framework, a rod loosely connected to the eye and passing through the eye of the plunger, and a coiled spring interposed between the eye-bolt and guideeye, substantially as specified.

3. In a baling press, the combination with the baling-chamber and its plunger, of a sweep fulcrumed between its ends at the front end of the plu nger and provided with inner guides at opposite sides thereof, a retraoting spring for the plunger, a triangular plate pivoted between its ends to the plunger, said plate having its front end engaging the guides in the sweep, and means for limiting the oscillations of the plate, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto aliixed my signature in the presence of two witnesses.
